T-Mobile Launch Guide For "The Shack"

Looks like BGR got their hands on T-Mobile internal launch guide for Radio Shack AKA "The Shack". It's said that these 11 devices will launch two weeks from tomorrows date (18th). Something odd about the lineup is that it's missing the soon to be released 8520. We all know it was officially announced to be released on the 5th which is tomorrow, so why isn't "The Shack" gonna have it when they launch selling T-Mobile devices? Doesn't sound like a good idea on T-Mobiles part if you ask me.
